Abstract

La présente invention concerne un matériau actif pour électrode positive, ledit matériau ayant pour composition la formule chimique (1) LiFe(P1-XO4) dans laquelle P a un rapport molaire de 0.910 à 0.999. Le matériau actif pour électrode positive de la présente invention a une efficacité de fonctionnement ramenée au niveau de l'efficacité de fonctionnement d'un matériau actif pour électrode négative, laquelle efficacité est relativement faible, et peut améliorer la densité d'énergie du matériau actif pour électrode positive. En outre, puisque Fe2+ et Fe3+ coexistent dans le matériau actif pour électrode positive, le rapport molaire (1-x) de phosphore (P) étant ajusté à moins de 1, tout effondrement structurel dû à la déficience de phosphore (P) est empêché, la conductivité ionique est améliorée pour offrir des capacités supérieures de régime de charge/décharge, et la chute de tension ohmique est supprimée pendant le chargement/déchargement, ce qui améliore la densité d'énergie.
